i think you're saying once course selected shouldn't displayed on next page student can have on other courses?

if can use following sql query on next page don't want display student's completed course.

select * course id != $course_id

let me know if i'm wrong. didn't comment out reputations low , stackoverflow didn't allow me to.

[edited]

this complete code.

your select php file:

//assuming logging in students username or email id, if store username in session logging in. <?php      $user = $_session['username'];     include("includes/connect.php");      if (isset($_post['submit'])){      $course_id= $_post['course_id'];     $course_title= $_post['course_title'];     $course_credits= $_post['course_credits'];     $course_status= $_post['course_status'];      $query="select course.id,course.title,course.credits,course.status course course.username = $user";      $run=mysqli_query($conn,$query);      while($row=mysqli_fetch_array($run)){     $course_id= $_session['course_id'] = $row['course_id'];     $course_title=$row['course_title'];     $course_credits=$row['course_credits'];     $course_status=$row['course_status']; }     ?>

now in next php file :

$already_selected_course = $_session['course_id'];  query should like.  $query = "select course.id,course.title,course.credits,course.status course course.id != $already_selected_course";

this it. note: solution might contain errors of brackets etc logic clear.

for better knowledge have @ mysql complete video series here!

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
